Can I be honest with you, after writing and selling lots of ebooks myself (giving alot of them away for promotional purposes) Ebooks that sell are written to provide a solution to a problem, an answer to a question. 99% of the time, if an ebook isn't written about this, then it's not going to do well at all, no matter how good the actual book is written. The types of ebooks people buy are stuff like: "How to lose ten pounds in 10 weeks" or "how to get 2000 visitors to your site daily" stuff like that. People don't generally get ebooks for reading pleasure, but to get something done. I hope that helps.
